showing one of the links of the endless feed chain.

Corresponding parts in the several figures are denoted by likecharacters of reference.

The machine includes a main or principal frame A which is stationary,and a movable or adjustable frame B. The main frame is provided withbearings for transversely disposed rock shafts 1 and 2 havingbell-cranks 343 connected by a link or connecting rod L whereby motionis transmitted between the rock shafts so that the latter will rock inunison. The rock shafts 1 and 2 are provided with radially extendingarms 5 that are pivotally connected with brackets 6, which latter formparts of thc frame struc ture B. The latter', as will be seen, is thussupported by the rock shaft-s l and 2, in such a manner that verticaladjustment of the entire frame structure B may be effected byoscillating the rock shafts in their bearings. The rock shafts 1 and 2are provided with arms 7 carrying weights S whereby the vframe structureB and its related parts will be counterpoised so that verticaladjustment thereof may be effected without strenuous exertion on thepart of the operator, the adjustment being e'll'ectcd by means of ahandlever 9 connected with the rock shaft 1 which is located at thefront end or feed end of the frame of the machine where the attendant isstationed when the machine is in operation. For the purpose of securingthe frame structure B at the desired adjustment, the handlever 9 isprovided with a stud 1() guided in a segmental slot 11 in a bracket 12equipped with a tail nut 13 which may be tightened against said bracket.A suitable gage or indicator 14 is also provided which in practice willbe inscribed with a scale that serves to indicate to the-operator theprecise point of adjustment of the frame B.

The main shaft 15 for driving the machine is supported for rotation inbrackets 16 upon the rear end of the main frame A, said shaft beingldriven from any suitable source of power, in any suitable and convenientmanner; for instance, by a belt engaging a band wheel 17 upon saidshaft. The frame A is provided with bearings :for a countershaft 18having a band wheel 1) which is connected by a belt 20 with the mainshaft 15 from which motion, at reduced speed., will thus be transmittedto the countersha'ft. The band wheel 19 is loosely mounted upon thecoun- IOO ings, said links being tershaft 18, but may be connected withthe latter, so as to revolve therewith, by means of a clutch 22 ofordinary construction, said clutch being operable by means of a shippinglever 23 fulcrumed upon the main frame at 24 and extending to the frontend of the machine within convenient reach of the operator.

The countershaft 18 is provided with links or radius bars 25 supportinga floating shaft 26 carrying a spur wheel 27 meshing with a pinion 28upon the countershaft from which motion will thus be transmitted, atreduced speed, to the floating shaft 26 in any position occupied by thelatter. The floating shaft 26 is connected by means of'links 29 with ashaft 30 j ournaled in suitable bearings upon the vertically adjustableframe B, and the shafts 26 and 30 are provided with sprocket Wheels 3l'and 32 connected by a link belt 33 whereby motion will be transmitted aswill be readily understood.

The shaft 30 is located near the rear end of the frame B, and acorresponding shaft 34 is supported in suitable bearings near the frontend of said frame. Said frame is also provided near its front and rearends with depending brackets 35 and 36 affording bearings for shafts 37and 38. The shafts 30, 34, 37 and 38 carry sprockets 39 over which isguided an endless flexible element consisting of a chain 40 whichconstitutes the feed device of the machine. The chain 40 is provided atintervals with specially `constr-ucted links 4l, shown in detail in Fig.l of the drawprovided with transverse flanges 42 upon which cross pieces43 are bolted or otherwise secured 5 said cross pieces serving to engagethe segments that are to be operated upon for the purpose of pushing orfeeding the same past the :saws whereby the ends of said segments. aretrimmed or cut at the re uisite angle, as will be hereinafter more fullydescribed. The edges of the links are beveled or dove-tailed as will beseen at 44, and a correspondingly beveled or dove-tailed guide-way 45,.best seen in Fig. 4 of the drawings, is formed in the bed of the frameB for the purpose `0f guiding said links.

The frame B is provided near its fron-t and rear ends, respectively,with transverse dovetailed grooves 46 and 47 in each of which is guideda pair of oppositely movable slides thus designated respectively 48, 48aand 49, 49a. In suitable bearings beneath the transverse grooves 46 and47 are j ournaled transf verse shafts 50 and 5l, each provided withoppositely threaded portions engaging nuts 52 that are fitted inrecesses 53 in the several slides. The transverse shafts 50 and-51 areprovided with bevel pinions 54 meshing with corresponding bevel pinions55 upon la longitudinally disposed transmission shaft 56 whereby motionis transmitted between the shafts 50 and.51, the former of said shaftsis provided withI a hand Wheel 57 whereby it may be convenientlymanipulated for the purpose of eecting simultaneous adjustment of theslides 48, 48a and 49, 49a.

Each of the slides 48, 48a and 49, 49a carries a vertically movable rodor member 58 having at its lower end an anti-friction member such as awheel 0r caster 59. cally movable members 58 are provided with heads 60that are connected in pairs by means of longitudinally disposed rodswhich I call the track bars 61 these track bars are for the purpose ofsup orting the segments that are to be operatedpupon while they arebeing conveyed from one end of the machine to the other by means of thefeed chain. The head 60 upon one of the vertically movable members 58 atone side of the machine also supports an upstanding flange constitutinga gage plate 62, clearly seen in Figs. 2 and 4 of the drawings.

The vertically movable members 58 are supported upon a guide byadjusting levers 63 which are fulcrumed, in pairs, adjacent to thetransverse shafts 50 and 5l, said levers being provided with short arms64 extending inwardly in the direction of the longitudinal 'center ofthe machine, and carrying antifriction rollers 65 that are in engagementwith c-ams 66 mounted upon the longitudinal shaft .67, by the partialrotation of which the levers 63 will be rocked upon their fulcra, thusraising .or lowering the vertically movable members 58, and the barsyconnected therewith g it being understood that the movement of thelevers and the vertically movable members is simultaneous .and uniform.The shaft 67 carries pinions 68 meshing with similar pinions 69 upon alongitudinal shaft 70 connected by miter gearing 71 with a transverseshaft 72, the `latter carrying at one end a hand-lever .73 whereby itmay be conveniently manipulated to effect the desired adjustment of thelevers 63 the vertically movable members 58 and related Aarts.

p It will be seen from the foregoing description .that by simply`manipulating the shaft 50 by means of the hand-lever 57, the slidescarrying the vertically movable members :58 may be transverselyadjusted, said slides 'moving in pairs, in opposite directions, thusadjusting the track bars 6l at various distances apart; when this.adjustment is being effected, the vertically movable members 58 willtravel along the up er surfaces :of the -adjusting levers 63, whic-a-reusually in oppositely inclined positions `at the two sidesof themachine; by reason of this fact, it ebvious that transverse adjustmentof the ltrack bars will at the same time Vresult in .a verticaladjustment of said bars but independent vertical adjustment ofthe trackbars may be effected, when desired, by manipula- The vertil IOO IIS

tion of the shaft 72 having the hand-wheel 73 whereby, through theintermediate mechanism provided for the purpose, the adjusting levers 63will be rocked upon their respective fulcrums, thus raising or loweringthe vertically movable members 5S, and consequently effecting verticaladjustment of the track bars. It is considered to be within the scopeofthe invention to provide conveniently located gages or scales wherebythe exact adjustment of the parts will be visually ndicated to theoperator, who will thus be enabled to set or adjust the parts with theutmost nicety according to the work that is to be performed.

The trimming or mitering of the ends of the segments is effected bymeans of a pair of circular saws 74 mounted upon arbors or mandrels 75which are supported adjustably in oppositely inclined positions at thesides of the machine. The lower, inner ends of the mandrels 75 arejournaled in bearings 76 hingedly supported upon the frame B; the outer,upper ends of the mandrels 75 are journaled in sleeves 77 pivotallysupported by means of trunnions 78 in forks 79 at the upper ends ofvertically adjustable rods SO that are guided in suitable bearings 81upon the frame A. The rods S0 are provided with racks 82 engaged by spurwheels S3 upon a shaft 84 journaled transversely in the Vframe A, saidshaft being connected by miter gearing 85 with a vertically disposedshaft 86 which inv turn is connected by miter gearing S7 with alongitudinally disposed shaft S8 havng at one end a hand wheel S9whereby it may be conveniently manipulated to effe-ct the desiredvertical adjustment of the forked rods S0 whereby the bearings for theouter ends of the saw carrying mandrels are supported. The shaft S4carries a grooved pulley or drum to which is attached one end of afiexible element such as a cord or cable 91 which, after being woundupon the drum or pulley, is guided over a suitable guide member such asa pulley 92, said flexible element carrying at its free end a weight 93whereby the saw carrying mandrels are counterpoised so as to facilitatetheir adjustment by the operator.

It is obvious that within the scope of the invention ordinary well knownmeans may be provided for the purpose of locking the shaft 88 at variousadjustments in order to prevent accidental displacement of the saws; itis also obvious that a scale or indicator may be employed for thepurpose of visually indicating to the operator the exact pitch or angleto which the saws have been adjusted.

T he saw mandrels are provided with pulleys or band wheels 94: which areconnected by belts or bands 95 with driving pulleys or band Wheels 96upon the main shaft 15 from which motion will thus be transmitteddirectly to the saw mandrels; for the purpose of imparting to the belts95 the requisite twist, to prevent them from slipping from the mandrelpulleys, said belts are guided in contact with cone pulleys 97 idlysupported upon a shaft 9S.

lhc vertically adjustable frame B is provided at suitable distances fromits front and rear ends with pairs of uprights 99 which are connected,in pairs, by cross-bars 100. The cross-bars are provided with bearingswherein are journaled swivel nuts 101 provided with sprocket wheels 102which are connected by a link belt 103 whereby said nuts may be rotatedin unison; said nuts are also provided with hand wheels 104 whereby theymay be conveniently manipulated, for the purpose of effectingsimultaneous and uniform vertical adjustment of threaded rods 105 thatextend through the nuts. Said threaded rods carry at their lower ends asocalled brush 106 consisting` of a back 107 equipped with a pluralityof downward projecting flexible resilient tongues 10S, the lowerextremities of which will thus be adjustably supported a suitabledistance above and intermediate of the longitudinally disposed trackbars 61.

From the foregoing description taken in connection with the drawingshereto annexed the operation and advantages of this invention will bereadily understood to those skilled in the art to which it pertains.

The previously prepared segments or blanks that are to be operated upon,and which in the drawing are designated by the letter S, are placed uponthe track bars 61 at the feed end of the machine, where they may bedeposited in stacks or bunches, it being only necessary to take carethat they are properly placed in contact with the upstanding flange orguide plate 62. It is also obvious that the adjustable parts of themachine, namely, the track bars 61, the saws 74, and the brush 106 musthave been previously properly adjusted according to the work that is tobe performed. rl`he saws having been set in motion, the feed mechanismis then started by o )erating the shipping lever 23 to throw the cutchmember '22 into engagement with the pulley or band wheel 19 so as tolock the latter upon the countershaft 22 3 the endless feed chain 40being thus set in motion, the links of said chain having the crosspieces if3 will engage the blanks or segments and carry the latter alongthe track bars 61, beneath the brush and past the saws 74, which latterwill trim or cut the ends of the segments at the proper angle, thesegments or blanks being meanwhile held in position upon the track bars,with sufficient security, by the flexible resilient tongues of the brushmember, the latter may be of any desired length, and may serve to holdthe segments in position upon the track bars until they are dischargedover the ends of the IOO IIO

latter at the rear or tail end ofthe machine.

The saws 74 may, when desired, be adjusted upon the shafts or mandrels,longitudinally of the axes of the latter, in order to enable segments orblanks of various lengths to be operated upon, lt Will be noticed thatblanks or segments, greatly varying in length, may be efficientlyoperated. upon by this machine owing to the fact that the track barsWhich constitute the bed over Which the segments are guided areadjustable toward and away from each other, thus enabling them to be soadjusted as to support the blanks or segments near the ends of thelatter Where they are subjected to the strain E of the saws; thematerial that is to be operated upon Will thus be very firmly andsecurely supported under all circumstances.

When the track bars are moved apart from each other, for the purpose ofsupporting blanks or segments of considerable length, the inner ends ofthe saw carrying mandrels will be simultaneously moved in an upwarddirection, and the saWs Will thus be moved upwardly-together with thetrack bars so as to occupy approximately the same relative position tothe track bars Which is obviously desirable in order to enable themitering to be performed at all circumstance Without eX- posing aconsiderable portion of the saws to frictional contact With the ends ofthe material that is being cut.

The general construction of the machine is simple, and the componentparts are so arranged and assembled as to be under convenient control ofthe operator.
